Anomalous left coronary artery from the pulmonary artery
Anomalous left coronary artery from the pulmonary artery is a rare congenital anomaly in which the left coronary artery branches off the pulmonary artery instead of the aortic sinus. After birth, the pressure in other coronary arteries will have a pressure that exceeds the LCA and collateral circulation will increase. This, ultimately, can lead to blood flowing from the RCA into the LCA and into the pulmonary artery, thus forming a left-to-right shunt.
The syndrome is named for Edward Franklin Bland, Paul Dudley White, and Joseph Garland.
